Why doesn't AVG provide me with a firewall to protect my PC?

Pauline, What exactly did you purchase from AVG?.. The firewall actually only features in the AVG Internet Security (http://www.avg.com/ww-en/internet-security) [Scroll Down].

I have no firewall.  I would not have ordered your protection if I didn't have a firewall.  I think its time to  look elsewhere for protection.  Im not paying $60 more for something you should have provided me with in the first place.

Hello Pauline. Thank you for contacting us. I have checked your records and found you have purchased AVG Anti virus. AVG Anti virus does not include firewall protection. It is offered only with AVG Internet security. Please click on ( http://www.avg.com/ww-en/internet-security ) to know the difference between AVG Antivirus and AVG Internet security.
